 Microwave Ceramics and Modules 3-Pole Filter for WLL Base Station TX Filter
Data Sheet
Filter B69843N3457A120
Application RF filter for WLL (Wireless Local Loop) Features SMD filter consisting of coupled resonators with stepped impedances MgTiO3-CaTiO3 (r = 21 / TCf =010 ppm/K) with a coating of copper (10m) and tin (>5m) Excellent reflow solderability, no migration effect due to copper/tin metallization ESD insensitivity and ESD protecting due to filter characteristics Index Page 2 Component drawing Footprint Page 3 Characteristics Maximum ratings Typical passband characteristic Page 4 Processing information Soldering requirements Delivery mode
